Technology: RF - Bluetooth Basics

Wireless RF systems use an antenna to generate and transmit electromagnetic energy away from the device.

In these types of systems all of the transmission energy is designed to radiate into free space.

This type of transmission is referred to as “far-field” because the energy persists at distances far from the transmitter.

The properties that make far-field RF systems ideal for long range communications are a disadvantage for secure, short-range wireless systems.

Technology: FreeLinc BasicsNear Field Magnetic Communication

FreeLinc Near-Field Magnetic Induction (NFMI) is a wireless protocol that communicates by coupling a low-power, non-propagating magnetic field between devices.

Magnetic Induction uses a transmitter coil in one device to generate and modulate a magnetic field, and a receiver coil in another device to measure the magnetic field modulations.

NFMI systems are designed to contain the transmission energy within the localized magnetic field – creating a communication “bubble” around the user.

This magnetic field energy resonates around the communication system, but does not radiate into free space.

This type of transmission is referred to as “near-field.”

Technology: FreeLinc NFMI BenefitsReliable Signal Quality and Clear Transmissions

FreeLinc NFMI energy is contained in a magnetic field, forming a tight communication “bubble” which provides a high signal-to-noise ratio between paired devices.

RF waves used in most wireless communication systems are susceptible to multi-path fading, reflection, and environmental conditions.

Magnetic fields are highly predictable, NFMI energy saturates its environment, penetrating the human body, walls, concrete, and

earth;providing reliable signal quality and clear audio transmissions.

Technology: FreeLinc NFMI Benefits

Lower Power Consumption and Long Battery Life

FreeLinc NFMI systems use substantially less power than RF communication systems.

In a far-field RF system, all of the transmission energy is designed to leave the transmitter

antenna and radiate into free space.

There is no reuse of power in these types of far-field systems.

NFMI systems operate by resonating a magnetic field around the transducer antenna. In this type of system the transmission energy remains in or around the transmitter circuitry.

This behavior allows NFMI systems to reuse the transmission energy, and thereby consume less power than comparable

RF communication systems which must continually generate and propagate an electromagnetic wave into free space.

The natural power saving properties of magnetic induction allow FreeLinc wireless systems to provide up to five times more battery life than other wireless systems.

 

Technology: FreeLinc NFMI Benefits

Reduced Frequency Contention

Most RF systems share their bandwidth using time or frequency allocation due to the long range of RF signal propagation.

The tight communication bubble of magnetic-field energy allows for a large number of NFMI systems to be co-located.

Simultaneous access to a defined frequency spectrum is accomplished by dividing space – not by dividing time or frequency.

Technology: FreeLinc NFMI Benefits

Improved Security – No Interception

NFMI systems are designed to work in the near-field. Therefore, the far-field power levels of these systems are up to 10,000 times less than a typical RF device such as Bluetooth, which is designed to intentionally emit far-field waves.

As the distance from an NFMI system increases, the emission levels rapidly fall below ambient noise floors, improving security and making interception extremely difficult.

Getting Started

Attach the Adaptor to the Radio

Attach the Adapter to your radio and turn your Volume to 70%

Turn ON Adapter

Set the On/Off Toggle Switch to the ON

position

This will automatically silence the speaker on your portable radio and

route all communications to the FreeLinc Remote

Pairing Remote Device

To Initiate Pairing, place the Remote DeviceWithin 10 inches of the Adapter, press and hold

Both Volume Buttons for 3 seconds

The Adapter Indicator Light will change from Flashing Red to Flashing Green,

indicating a successful pairing.

ADAPTORIndicators and Behavior

REMOTE DEVICETones and Behavior

The remote device is constantly sending back a signal to the adapter to make sure they still have connectivity.  When the

remote device does not receive confirmation from the adapter, your remote device will go to stand-by after 2 to 5 minutes. 

OR

If the remote device and radio/adapter are out of range, the indicator light on the adapter will indicate red. To take it out of

standby, depress the PTT on the remote device before powering up the radio/adapter or bring the remote device back in range.

If there is no power to the adapter, the LED indicator will be off.

Facts You Should Know

*For encrypted pairing, please ask your FreeLinc representative.

Facts You Should Know

Although not common, changes in your environment may cause your magnetic field to drift. If this

happens, you may hear popping or noise in your audio link.

This can be easily fixed by recalibrating your remote device and adapter by re-establishing the pairing.

Facts You Should KnowIn all wireless technology, there is some level of spurious radio

frequency. The level found in FreeLinc’s NFMI is the same as in some Radio Frequency Identification (RFID) devices.

RFID readers can be found at the cash registers of many convenience stores, drug stores, or throughout a Wal-Mart or

Target (price look-up stations). They can be found in buildings with secure entry and in equipment rooms for checking in and out

weapons, radios, etc.

When you come within close proximity of these devices you may hear the loss link alert tones.

Once you pass the RFID reader or step back 1 to 2 steps, the communication link will automatically re-establish.

Facts You Should KnowIf you come within three feet of another NFMI based device you may experience

some static or hear the link loss alert tones.

This is remedied by either moving away from the other user or bringing your

adapter closer to your remote device which will automatically shrink the size

of the communication bubble.
